Just recently having had some fun with the terror drill portraying pot farmers leading an armed takeover of Shasta Dam, at least the cartels are using their ingenuity to actually try and move some drugs.This past Thursday, federal authorities discovered another intricate tunnel system, complete with branches leading to warehouses, lighting, and ventilation connecting San Diego and Tijuana. The fact this is the second tunnel found in three weeks, with 45 tons of marijuana seized altogether, says the feds are on a role, and at least accomplishing something at the border other than busting Willie Nelson. The fact the cartels can run a safer underground operation than Massey Energy says something too, but that's for another column. The other interesting part of this bust to me was the math involved with the amount seized, as DEA Special Agent in Charge Ralph Partridge said the haul of 20 tons was the equivalent of 17 million joints. Let me get this straight...20 tons = 17 million joints. Bet the street value must be near a gazillion dollars. I would love to see how long it took them to roll up 20 tons to arrive at that number. Not to mention, I kind of wish I had kept track of all the weed I've smoked...I mean, I know I am nowhere near 20 tons, but what can I say? I am curious nonetheless...
